**Exercises: Solve the exponential Equation rounding decimal answers to the thousandths place.**

3^{x}=12

\(\begin{array}{|rcll|} \hline 3^x &=& 12 \quad & | \quad \log() \text{ both sides} \\ \log{(3^x)} &=& \log(12) \\ x\log{(3)} &=& \log(12) \quad & | \quad : \log{(3)}\\\\ x &=& \dfrac{\log(12)} {\log{(3)}} \\\\ x &=& \dfrac{1.07918124605} {0.47712125472} \\\\ x &=& 2.26185950714 \\\\ \mathbf{x} &\mathbf{\approx}& \mathbf{2.262} \\ \hline \end{array}\)
